October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Throttle Position Sensor (TPS)

TPS, located on throttle body, is a variable resistor. Movable contact inside sensor rotates with throttle valve shaft, sensing throttle valve opening. As throttle valve shaft rotates, sensor output voltage changes. Based on signal generated by sensor, ECM detects throttle valve opening and determines engine operation mode (acceleration or deceleration).
